Referring to the drawings, the device is shown to include an intermediate casing 7 in the upper portion of which is inserted a lock collar 8 through which slidably passes an operating shaft 9.

Attached to the lower end of the shaft 9 is a plate 10 having an upturned portion 11 to which is attached a knife blade 12, and an upturned portion 13 having a right angular flange 14-. A pad 15 preferably of rubber, is attached to the underside of the plate 10.

Attached to a loop 16 an integral part of the plate 10, is one end of the tension springs 17, having their other ends connected with a pin 18 mounted in the walls of the casing.

Shaft 9 has attached thereto a transverse r pin 19 adapted to engage a notch 20 on a right angular lever 21 pivoted at 22 to the arm 23 of :grooves 28 ie f a corrugated arcuate guide Ppiatefil.

I i A I The plunger 39 h as a further reduced, portion 45 between the portion 41 and the piston The lower end of the cylinder '42 contains'a ball 46 adapted to close the aperture 47 in ther-bottolnof thecylinder against the flowdf Water backto chamber 48 whenipiston ll t i s descending and; portion 41.is discharging water through tube 43 to'openirrg 50.

:Irr operation, the plunger '92 is depressed to cause; pi'1r1 '9 to engage the notch 20 in lever 21 v to iswing the :arms 23 downwardly so that the fingers 26 on the plate 29 may engage in the perforations 49 which divide the stamps.

By this means the stamps are accuratelyfed downward since there will be no feeding movement until the fingers 26 have engaged a row of perforations 49. When the arm 23 is moved down a predetermined distance, that is the distance between perforations in the stamp strip, into a position as shown in Figure 5, directly beneath the rubber pad 15, the pin 19 becomes disengaged from'the notch20' on account of the angular change of the position of the pivot pin 22, and springs 25 return the yoke arms 23 and levers21 to their initial position.

As the plunger moves downwardly the compression spring40, in conjunction. with springs 25 the ends of which are secured'to the levers 21 and to theprongs 53 on bridge '38, force the plunger 39 downwardly to a position whereby the Chamois piston 44 will not cover the opening to tube 43 in the cylinder 42, and water surrounding the'reduced portion 45 of the plunger 41 is forced through tube 43 on to the surface to which the stamp is 'At the same time the plunger 9 continues .downwardy and, the knife blades 12 and 37 shear-the stamp off at. the point 52 along the line of perforations 49,-andthe pad 15 presses the stamp firmly upon the moistened surface. I

The plunger 9 is returned automatically to its raised position by tension springs 17 which carry upwardly with them the plunger 39, closing the opening to tube 43 in cylinder 42 to prevent water leaking from tube 43 at opening 50; and to retain anamount of water at reduced portion-45 toact as a cushion to force water out of opening in cylinder 42 through tube 43 to opening 50 when water is forced by piston 44 from chamber 51 on the Having thus described my invention, what I claim as new and desire to ters Patent, is: j

between the Wires, said plate being attached to the yoke, a plunger,and means associated with the plunger and yoke to rotate the latter 'when the plunger is depressed.

3. In a machine of the class described, a corrugated guide, plurality of resilient wires bearing against the guide, a pivoted yoke having projections adjacent the guide, and means to swing the yoke.

.4. In a machine of the class described, a plunger, resilient means for holding the plunger in a raised position, a transverse pin mounted-on theplunger, a pivoted yoke, a

lever pivoted on said yoke and having a notch adapted to be engaged by the pin when the plunger is depressed, and resilient means for retaining saidlever in a predetermined position when the plunger is in a raised position.
